ADIC & DELL Firmware overwrite on ML6000?

We recently purchased a DELL ML6010 which is basically an ADIC i500 with the DELL badge and firmware. All of our libraries are ADIC and we wanted to use one of our LTO3 drives from an ADIC i500 in the DELL ML6010. Fits perfectly, however the library rejects it and since it's the only drive in the library I can't rewrite the ADIC firmware with DELL.  So.... I'm wondering if its technically possible to overwrite the DELL firmware with the latest ADIC firm therefore making the tape library an ADIC i500. Has anyone done this before? I know it's against support etc, possible risk of curruption etc.. but we don't have any support anyway for this unit.
